Correct,

Once you had armed your door, you then went to opposite door to check that the crew member had correctly armed it as well. But as mentioned cross checking was dropped sometime ago by Qantas.

Singapore Airlines say "Set doors to Automatic" but it is the same as arming a door.


The 737/767 over wing exits and the 767RR doors 3 are always armed. If you open them on the ground, the slides will inflate.

More from the ABC. It appears that a chunk of the aircraft is missing:

Speaking from the Manila airport, passenger Dr June Kane says she heard a loud bang from underneath the plane, and saw debris fly through the cabin. "I'm looking at the plane now and on the left hand side, just forward of the wing, there's a gaping hole from the wing to the underbody," she said.
"It's about two metres by four metres and there's baggage hanging out so you assume that there's a few bags that may have gone missing."

Not nice!

OK.

I see bags....

Bags are usually inside rolling cargo containers.

how did they get out, I note that some of those containers are pretty flimsy with a vinyl side curtain but also have seen them in bomb tests designed to contain an explosion.

anyway good thing it was'nt on the usa run as at 10000 feet the fuel burn can be an issue to avoid landing on an aqua tarmac!

Qantas damage control will be interesting.

Well,from what l got told he said that even if the main doors were unlocked, it would be highly unlikely the door would open because of the pressure difference.
Look, just what he said to me. Weather true or not, lets google it.....
And the 5 ton figure has been used before. I think that myth busters did something like this once too.

Sorry, but NOT TW800. The official NTSB finding is that there was an explosion in one of the fuel tanks, but there are other theories (certainly nothing to do with doors opening).

And I think AI182 and PA103 are in a similar category, eg explosive devices. I guess you were just trying to be funny (and succeeded)...

Lets take TW800 off the list then rather than drag the thread off topic

You might however want to take a look at this http://www.ntsb.org/Wiringcargodoorl...ovcombined.pdf after after looking at the photo just published of the damage to QF30, its early days yet and pure speculation but cargo doors could get some more attention as a result and there is some interesting historical data contained within that reference! Food for thought, then again I could be way off track as well. As far as I can see there is no door in the area of the damage from the new photo so who knows.
